NCT07322133

Brief Summary

This pilot randomized clinical trial compares dopamine and norepinephrine as first-line vasoactive therapies in term and late preterm neonates with pulmonary hypertension associated with hypoxemic respiratory failure and systemic hypotension. Systemic hypotension is a common and clinically significant complication of persistent pulmonary hypertension of the newborn (PPHN) and frequently requires vasopressor support to maintain adequate systemic perfusion. Dopamine is commonly used in this setting; however, prior animal experimental and clinical data suggest it may increase pulmonary vascular resistance, potentially worsening right ventricular afterload and hypoxemia. Norepinephrine may preferentially increase systemic vascular resistance with less effect on the pulmonary circulation. This study evaluates short-term hemodynamic and oxygenation responses following initiation of dopamine or norepinephrine.

Outcome Measures

Primary Outcomes (3)

  • SAP/PAP ratio

    Ratio of systemic arterial pressure to pulmonary arterial pressure (SAP/PAP)

    Within 30 hours of vasopressor initiation.

  • LV Cardiac output

    Left Ventricular Cardiac Output calculated with echocardiography

    Within 30 hours of vasopressor initiation

  • Oxygenation Indices

    FiO₂ (fraction of inspired oxygen), SpO₂ (peripheral oxygen saturation), PaO₂ (arterial oxygen partial pressure), OI (oxygenation index), OSI (oxygen saturation index)

    Within 30 hours of vasopressor initiation

Secondary Outcomes (3)

  • Use of inhaled nitric oxide (iNO)

    Within 30 hours of vasopressor initiation

  • Need for additional vasoactive agents

    Within 30 hours of vasopressor initiation

  • Echocardiographic markers of heart function

    Within 30 hours of vasopressor initiation

Study Arms (2)

Dopamine Arm

ACTIVE COMPARATOR

Infants in this group will receive dopamine as their first-line vasopressor. Continuous intravenous dopamine infusion will be initiated at 5 mcg/kg/min and titrated to achieve gestational age appropriate mean arterial blood pressure targets (maximum 20 mcg/kg/min).

Drug: Dopamine administration

Norepinephrine Arm

ACTIVE COMPARATOR

Infants in this group will receive norepinephrine as their first-line vasopressor. Continuous intravenous norepinephrine infusion initiated at 0.02 mcg/kg/min and titrated to achieve gestational age appropriate mean arterial blood pressure targets (maximum 1 mcg/kg/min).

Drug: Norepinephrine

Interventions

Infants meeting the inclusion criteria who are randomized to norepinephrine arm will receive norepinephrine infusion starting at 0.02 mcg/kg/min, titrated to mean arterial pressure targets based on gestational age, max dose 1 mcg/kg/min.

Norepinephrine Arm

Infants meeting the inclusion criteria who are randomized to dopamine arm will receive dopamine infusion starting at 5 mcg/kg/min, titrated to mean arterial pressure targets based on gestational age, max dose 20 mcg/kg/min.
